A Correct answer
Explanation

Spinel (MgAl2O4) is the mineral of Mg and aluminium. Felspar (KAlSi3O8) is the mineral of potassium and aluminium. Cerussite (PbCO3) is the carbonate ore of lead. Malachite (Cu(OH)2.CuCO3) is the carbonate ore of copper. Hence, the correct sequence of the codes is A - 1, B - 3, C - 2, D - 4.
